Source Code
Unison is hosted at SourceForge.

The Unison source code contains raw the SQL schema, Perl modules, scripts, Makefiles for data loading, and a lot more. Please see the subversion instructions on SourceForge for information about obtaining the source code. You may also browse the subversion repository with viewvc on SourceForge.

Database Dumps
The public database dumps contain non-proprietary sequences and predictions. This typically includes all sequences from all species and all sources available at the time of release, as well as predictions on most human, mouse, rat, yeast, drosophila, and zebrafish proteins. More can be computed and loading using the scripts in the source code distribution.
